A Treatise of Human Nature Quotes

“Generally speaking, the errors in religion are dangerous; those in philosophy only ridiculous.”
― David Hume, A Treatise of Human Nature

“Reason is, and ought only to be the slave of the passions, and can never pretend to any other office than to serve and obey them.”
― David Hume, A Treatise of Human Nature

“For my part, when I enter most intimately into what I call myself, I always stumble on some particular perception or other, of heat or cold, light or shade, love or hatred, pain or pleasure. I never can catch myself at any time without a perception, and never can observe any thing but the perception…. If any one, upon serious and unprejudic'd reflection thinks he has a different notion of himself, I must confess I can reason no longer with him. All I can allow him is, that he may be in the right as well as I, and that we are essentially different in this particular. He may, perhaps, perceive something simple and continu'd, which he calls himself; tho' I am certain there is no such principle in me.”
― David Hume, A Treatise of Human Nature

“The identity that we ascribe to things is only a fictitious one, established by the mind, not a peculiar nature belonging to what we’re talking about.”
― David Hume, A Treatise of Human Nature

“Any pride or haughtiness, is displeasing to us, merely because it shocks our own pride, and leads us by sympathy into comparison, which causes the disagreeable passion of humility.”
― David Hume, A Treatise of Human Nature

“We make allowance for a certain degree of selfishness in men; because we know it to be inseparable from human nature, and inherent in our frame and constitution. By this reflexion we correct those sentiments of blame, which so naturally arise upon any opposition.”
― David Hume, A Treatise of Human Nature

“Tis not unreasonable for me to prefer the destruction of the whole world to the scratching of my finger.”
― David Hume, A Treatise of Human Nature

“For my part, when I enter most intimately into what I call myself, I always stumble on some particular perception or other, of heat or cold, light or shade, love or hatred, pain or pleasure. I never can catch myself at any time without a perception, and never can observe any thing but the perception…”
― David Hume, A Treatise of Human Nature

“I may venture to affirm of the rest of mankind, that they are nothing but a bundle or collection of different perceptions, which succeed each other with an inconceivable rapidity, and are in a perpetual flux and movement.”
― David Hume, A Treatise of Human Nature

“Amidst all this bustle it is not reason, which carries the prize, but eloquence; and no man needs ever despair of gaining proselytes to the most extravagant hypothesis, who has art enough to represent it in any favourable colours. The victory is not gained by the men at arms, who manage the pike and the sword; but by the trumpeters, drummers, and musicians of the army.”
― David Hume, A Treatise of Human Nature

“Most fortunately it happens, that since reason is incapable of dispelling these clouds, nature herself suffices to that purpose, and cures me of this philosophical melancholy and delirium, either by relaxing this bent of mind, or by some avocation, and lively impression of my senses, which obliterate all these chimeras. I dine, I play a game of backgammon, I converse, and am merry with my friends; and when after three or four hours' amusement, I would return to these speculations, they appear so cold, and strain'd, and ridiculous, that I cannot find in my heart to enter into them any farther.”
― David Hume, A Treatise of Human Nature

“I cannot forbear adding to these reasonings an observation, which may, perhaps, be found of some importance. In every system of morality, which I have hitherto met with, I have always remark’d, that the author proceeds for some time in the ordinary way of reasoning, and establishes the being of a God, or makes observations concerning human affairs; when of a sudden I am surpriz’d to find, that instead of the usual copulations of propositions, is, and is not, I meet with no proposition that is not connected with an ought, or an ought not. This change is imperceptible; but is, however, of the last consequence.”
― David Hume, A Treatise of Human Nature

“The science of man is the only solid foundation for the other sciences. [All the other sciences] have a relation, greater or lesser, to human nature. ‘Tis impossible to tell what changes and improvements we might make in these sciences were we thoroughly acquainted with the extent and force of human understanding, and could explain the nature of the ideas we employ, and of the operations we perform in our reason.”
― David Hume, A Treatise of Human Nature

“The victory is not gained by the men at arms, who manage the pike and the sword; but by the trumpeters, drummers, and musicians of the army.”
― David Hume, A Treatise of Human Nature

“Should a traveler, returning from a far country, bring us an account of men wholly different from any with whom we were ever acquainted, men who were entirely divested of avarice, ambition, or revenge, who knew no pleasure but friendship, generosity, and public spirit, we should immediately, from these circumstances, detect the falsehood and prove him a liar with the same certainty as if he had stuffed his narration with stories of centaurs and dragons, miracles and prodigies.”
― David Hume, A Treatise of Human Nature

“We must therefore glean up our experiments in this science from a cautious observation of human life, and take them as they appear in the common course of the world, by men’s behaviour in company, in affairs, and in their pleasures. Where experiments of this kind are judiciously collected and compared, we may hope to establish on them a science, which will not be inferior in certainty, and will be much superior in utility to any other of human comprehension.”
― David Hume, A Treatise of Human Nature

“judgments. A mistake, therefore, of right may become a species”
― David Hume, A Treatise of Human Nature

“Tis from the resemblance of the external actions of animals to those we ourselves perform, that we judge their internal likewise to resemble ours; and the same principle of reasoning, carry'd one step further, will make us conclude that since our internal actions resemble each other, the causes, from which they are deriv'd, must also be resembling. When any hypothesis, therefore, is advanc'd to explain a mental operation, which is common to men and beasts, we must apply the same hypothesis to both.”
― David Hume, A Treatise of Human Nature

“There are instances, indeed, wherein men shew a vanity in resembling a great man in his countenance, shape, air, or other minute circumstances, that contribute not in any degree to his reputation; but it must be confess’d, that this extends not very far, nor is of any considerable moment in these affections. For this I assign the following reason. We can never have a vanity of resembling in trifles any person, unless he be possess’d of very shining qualities, which give us a respect and veneration for him. These qualities, then, are, properly speaking, the causes of our vanity, by means of their relation to ourselves. Now after what manner are they related to ourselves? They are parts of the person we value, and consequently connected with these trifles; which are also suppos’d to be parts of him. These trifles are connected with the resembling qualities in us; and these qualities in us, being parts, are connected with the whole; and by that means form a chain of several links betwixt ourselves and the shining qualities of the person we resemble. But besides that this multitude of relations must weaken the connexion; ’tis evident the mind, in passing from the shining qualities to the trivial ones, must by that contrast the better perceive the minuteness of the latter, and be in some measure asham’d of the comparison and resemblance.”
― David Hume, A Treatise of Human Nature

“A man who hides himself, confesses as evidently the superiority of his enemy, as another who fairly delivers his arms.”
― David Hume, A Treatise of Human Nature

“A man who hides himself, confesses as evidently the superiority of his enemy, as another, who fairly delivers his arms.”
― David Hume, A Treatise of Human Nature

“For if truth be at all within the reach of human capacity, it is certain it must lie very deep and abstruse: and to hope we shall arrive at it without pains, while the greatest geniuses have failed with the utmost pains, must certainly be esteemed sufficiently vain and presumptuous.”
― David Hume, A Treatise of Human Nature

“The other part of our system is a consequence of this. The parts, into which the ideas of space and time resolve themselves, become at last indivisible; and these indivisible parts, being nothing in themselves, are inconceivable when not filled with something real and existent. The ideas of space and time are therefore no separate or distinct ideas, but merely those of the manner or order, in which objects exist: Or in other words, it is impossible to conceive either a vacuum and extension without matter, or a time, when there was no succession or change in any real existence.”
― David Hume, A Treatise of Human Nature

“Thus if instead of saying, that in war the weaker have always recourse to negotiation, we should say, that they have always recourse to conquest, the custom, which we have acquired of attributing certain relations to ideas, still follows the words, and makes us immediately perceive the absurdity of that proposition; in the same manner as one particular idea may serve us in reasoning concerning other ideas, however different from it in several circumstances.”
― David Hume, A Treatise of Human Nature

“Secondly, we have several instances of habits, which may be revived by one single word; as when a person, who has by rote any periods of a discourse, or any number of verses, will be put in remembrance of the whole, which he is at a loss to recollect, by that single word or expression, with which they begin.”
― David Hume, A Treatise of Human Nature

“When we have found a resemblance [FN 2.] among several objects, that often occur to us, we apply the same name to all of them, whatever differences we may observe in the degrees of their quantity and quality, and whatever other differences may appear among them. After we have acquired a custom of this kind, the hearing of that name revives the idea of one of these objects, and makes the imagination conceive it with all its particular circumstances and proportions.”
― David Hume, A Treatise of Human Nature

“They are consequently conjoined with each other in the conception; and the general idea of a line, notwithstanding all our abstractions and refinements, has in its appearance in the mind a precise degree of quantity and quality; however it may be made to represent others, which have different degrees of both.”
― David Hume, A Treatise of Human Nature

“The abstract idea of a man represents men of all sizes and all qualities; which it is concluded it cannot do, but either by representing at once all possible sizes and all possible qualities, or by, representing no particular one at all. Now it having been esteemed absurd to defend the former proposition, as implying an infinite capacity in the mind, it has been commonly inferred in favour of the latter: and our abstract ideas have been supposed to represent no particular degree either of quantity or quality.”
― David Hume, A Treatise of Human Nature

“A very material question has been started concerning ABSTRACT or GENERAL ideas, WHETHER THEY BE GENERAL OR PARTICULAR IN THE MIND'S CONCEPTION OF THEM. A great philosopher [Dr. Berkeley.] has disputed the received opinion in this particular, and has asserted, that all general ideas are nothing but particular ones, annexed to a certain term, which gives them a more extensive signification, and makes them recall upon occasion other individuals, which are similar to them.”
― David Hume, A Treatise of Human Nature

“It is only from the selfishness and confined generosity of men, along with the scanty provision nature has made for his wants, that justice derives its origin.”
